I have raced indoors with the TBLE-02 in Eurotruck with no issue. The key to using an ESC without Lipo cut-off is to pay attention to how long you are racing/practicing the vehicle between full charges. At most typical indoor electric races/tracks a fully charged lipo battery will not discharge enough to be an issue. However there may be instances where someone is racing for an extended amount of time or on at a very large track where over-discharging may become an issue. I would recommend that everyone run a "test" race time, then check to see how much energy is left in the battery (either using their charger or a lipo battery checker).
I would recommend anyone who is concerned with over-discharging their lipo batteries when using an ESC without low voltage cutoff that they purchase an external lipo low voltage alarm. They can be found easily online.
